Title: Improvements in meat-mincing and sausage-making machines
IPC: B02C18/24
Filed: 1926-04-16
Abstract: 260,861. Wright, F. H., and Lewis, E. W. April 16, 1926. Guards, controlling. - In a mincing- machine or silent cutter of the type having knives revolving in a rotating bowl, the removable knife guard or cover for the bowl is provided with an arm having a lug or pin which engages a catch connected with and operating a clutch on the knife spindle so that the catch locks the cover in position when the. clutch is engaged. In Fig. 1, the mincer B and silent cutter C are driven from the same motor D. The mincer B is driven through worm gearing II, I, clutch K and worm M. The bowl of the silent cutter is driven through worm gearing H, I, clutch L and worm gearing N, P whilst the, knives G are driven direct through a clutch E. The knife guard a has an arm a<1> carrying a lug or pin b which is engaged by a sliding catch d carried by the machine frame. The catch is locked in the "open" position by a spring c which rises to engage the hook portion of the catch when the guard is lifted. The catch has a depending portion d<1> which, with a returning-spring, operates the clutch E, the catch being slidable by a pivoted handle g, h connected to a link k connected by a rocker to a crank on a shaft o<1> having a second crank p pivoted to the catch d. The other end of the link k is connected by a bellcrank l<1> to a slider l controlling the clutches K, L which are thus never engaged simultaneously. The handle g, h, is interconnected with the switch handle v (or belt striker) by a trip u so that the handle g cannot be moved for the release of the guard a until the switch v is in the " off " position, and similarly the switch cannot be moved to the " on " position unless the lever g is moved to lock the guard in its operative position. To -effect this, the arm h of the handle g is provided with a pin j on which one end of the trip rests, the other end having a cam face u<1> which bears against a similar face v<1> on the switch handle. The handle g is locked by the faces of the cog u<2>, on the end of the trip, engaging the pin i unless the trip, is first freed by operating the switch handle v which is itself locked, at times, by the trip u until the handle g is operated to free the trip. When the motor is switched off, the momentum of the knives may keep them rotating whilst the guard is lifted. To prevent this an additional safeguard, Fig. 3, in the form of a rheostat may be provided, the rheostat handle x and the handle g being interlocked by a trip w. In this construction, the motor is switched " off " by the handle v but the trip w holds the lever g, and consequently the, catch d, until the motor has slowed down sufficiently for the rheostat arm to swing back and release the trip w.
